Wouldn't it be wonderful if you could put up a protective shield to guard your children's teeth from decay? Think of the time and money you would save, not to mention the pain your children would avoid. Well, it turns out that you can put up such a protective shield — or at least, we, your dental professionals, can.

The natural protective mineral coating (the enamel) of a child's new teeth is more permeable to the acids that dissolve minerals and cause decay, so the new teeth are more vulnerable to tooth decay than mature teeth are. As a tooth's enamel matures it becomes more resistant and stronger. Thus it is important to protect the surfaces of the new teeth when they erupt (grow up through the child's gums).

The back teeth, particularly, often erupt with deep grooves in them. The backs of the top front teeth may also have such grooves, which dentists call “pits and fissures.” When the grooves are deep, they are hard to keep clean. Toothbrush bristles may not be able to reach to the bottoms of the grooves; and bacteria may gather in them, releasing acid byproducts that dissolve tooth enamel and start forming decay.

Dental sealants are among the preventive options we have in the war against decay in your child's new teeth. Regular tooth brushing and flossing, regular dental visits, application of fluoride, and low sugar consumption are also important in decay prevention techniques.

Sealants are protective coatings placed in the tiny pits and fissures to seal them off from bacterial attack. Some dentists routinely seal all permanent molar teeth and many primary (baby) molar teeth soon after they erupt.

Some dentists use sealants only when an examination shows that decay is just starting or very likely to start in a particular tooth. In such cases a minimal amount of tooth enamel is removed to eliminate any decay, and a mini-resin, invisible filling is applied.

Temporomandibular Disorder (TMD), which was formerly known as Temporomandibular Joint Disorder (TMJ), is a condition that is unusual in that it frequently is quite hard to diagnose, because it often mimics many other conditions. For this reason, many healthcare professionals refer to it as “the great imposter.” The condition arises when there are problems inside the temporomandibular joint and the muscles that attach to it causing pain. The pain is most often due to muscle spasm, thereby limiting the ability to open and close the jaw and to function normally. TMD can impact anyone and has a wide range of similar symptoms.

One of the common causes of TMD is stress, and it may manifest itself through clenching or grinding of teeth while awake or asleep. These habits are often completely subconscious until pointed out by a dental professional or sleeping partner. With stress-induced TMD, the pain often comes and goes in cycles. In other words, it may be present when you are stressed, seem to disappear for a while, and then reappear when you are stressed again. Another cause of TMD can be from an injury or trauma, such as a blow to the jaw. However, regardless of the cause of TMD, the pain is real and needs to be treated properly.

If you feel that you might have TMD, please let us know so that we can address your concerns, starting with a full history and conducting a thorough examination. Or if you are in constant or severe pain, contact us immediately to schedule an appointment. You can learn more about the signs, symptoms, and treatment options for TMD by reading “TMD — Understanding The Great Imposter.”

We in dentistry, advise parents to have an orthodontic evaluation some time before your child is 7 years of age. At this time, some of your child's adult teeth have come in and some primary (baby) teeth remain. This is a good time to check for developing problems. Treatment that begins while your child's teeth are coming in is called “interceptive orthodontics.” It provides an opportunity to achieve the best results in orthodontic treatment.

Once this evaluation takes place, it may mean that orthodontic treatment may need to take place in two-stages. A first phase of orthodontic treatment may prevent, intercept or minimize future orthodontic treatment. The first stage may be a process of guiding the growth of the jawbones that support the teeth. This is called “growth modification.” Then when the adult teeth have erupted through the gums, it may be time to do the second and final stage.

If a second phase of treatment is necessary it will probably require braces. These are small metal brackets that are bonded to the teeth. Thin flexible wires are threaded through them, and the wires are designed to push or pull on the teeth to provide a small amount of pressure that makes the teeth slowly reposition themselves within the jawbone. A light and controlled force pulling on a tooth causes new bone and ligament (the fibers that hold teeth in place) to be formed. These are living tissues that are constantly changing and remodeling themselves.

If you wait until your child's permanent (adult) teeth have all come in to start this process, it will be too late to correct some types of orthodontic problems, such as some types of malocclusions (“mal” – bad, “occlusion” – bite). It's better to work together with your child's stages of growth and development in order to have an optimum correction, both in looks and function.

You may be wondering whether a two-stage treatment costs twice as much. In fact, it is likely to be less expensive than a late one-stage treatment would be. Sometimes, the first stage may correct an underlying problem and make further treatment unnecessary. If a second phase is needed, it is likely to be easier and less costly.

It is not uncommon to have one or more teeth that are particularly sensitive to heat, cold, or pressure. If you have such a tooth, you probably want to know what caused it and what you can do about it. Here are some frequently asked questions, and their answers.

What causes teeth to become sensitive?
The most common cause of sensitivity is exposure of the tooth's dentin, a layer of the tooth's structure that is just below the outer protective layer (the enamel).

The dentin is sensitive but the enamel layer is not. Why?
The enamel is composed of minerals that are hard and protective. It is not living tissue and has no nerve supply. The dentin layer underneath is bone-like living tissue that does contain nerve fibers. It is protected by enamel above the gum line and by gum tissue in the area of the tooth's root, below the gum line. If the tooth's protective covering is reduced, the nerve fibers in that section of the dentin are exposed to changes in temperature and pressure, which they conduct to the inner pulp layer (nerve) of the tooth. The sensations that reach the tooth's interior pulp layer cause pain.

What causes exposure of the dentin layer in teeth?
Often the dentin is exposed by receding gums, causing areas of the tooth that are normally below the gum surface to be uncovered.

What makes gums recede?
One cause of receding gums is excessive, rough brushing techniques. This is particularly common in individuals who have a family history of thin gum tissues. Removing the film of bacteria called plaque requires only gentle action with a soft brush. This is one reason that we stress the value of learning proper and effective brushing techniques. Gum recession becomes worse after the uncovered dentin of the tooth's root is exposed to erosion from sweet and acidic foods and beverages, such as fruit juices.

Doesn't tooth sensitivity indicate decay?
Decay can also cause tooth sensitivity. As decay destroys a tooth's structure, it eventually invades the inner pulp of the tooth, causing greater and greater pain.

How can you prevent or reduce tooth sensitivity?
As we mentioned above, learn proper brushing techniques; we would be happy to demonstrate them. Use a toothpaste that contains fluoride, which increases the strength of the tooth's protective coating. In more serious cases, we can apply a fluoride varnish or a filling material as a barrier to cover sensitive areas. If you experience long-term tooth sensitivity, make an appointment for an assessment and diagnosis so that we can determine the cause and proper treatment.

As a Pro Football Hall of Famer and first runner up on the hit television show Dancing with the Stars, Jerry Rice has a face and smile that truly has star quality. However, that was not always the case. During an interview with Dear Doctor magazine, the retired NFL pro discussed his good fortune to have had just a few minor dental injuries throughout his football career. He went on to say that his cosmetic dentist repaired several of his chipped teeth with full crowns. Rice now maintains his beautiful smile with routine cleanings and occasional tooth bleaching.

If you have chipped, broken or missing teeth, or are considering a smile makeover, we want to know exactly what you want to change about your smile, as the old adage is true: Beauty is in the eyes of the beholder. This is one reason why we feel that listening is one of the most important skills we can use during your private, smile-makeover consultation. We want to use this time to ensure we see what you see as attractive and vice versa so that together we can design a realistic, achievable blueprint for your dream smile.

For this reason, we have put together some questions you should ask yourself prior to your appointment:

• What do you like and dislike about the color, size, shape and spacing of your teeth?
• Do you like how much of your teeth show when you smile and when your lips are relaxed?
• Are you happy with the amount of gum tissue that shows when you smile?
• Do you prefer a “Hollywood smile” with perfectly aligned, bright white teeth, or do you prefer a more natural looking smile with slight color, shape and shade variations?
